External Drive & Hall-Free Sensing Design
The MWS (G Series) adopts an external drive power supply design, paired with a Hall-free sensing scheme. This configuration delivers large output torque, making it suitable for heavy-load outdoor unit fan applications. The design also simplifies maintenance and drive customization, catering to diverse system requirements.
Compact & Durable Structure
Compared to conventional iron shell motors, this series features a more compact size, optimizing space utilization in outdoor units. The stator winding utilizes BMC molding technology, providing excellent waterproof and moisture-resistant performance. This extends the motor’s service life significantly, while also reducing overall noise by 2-3 decibels, minimizing outdoor noise interference.
Comprehensive Performance & Protection
With a power range of 450W-920W and an efficiency of 80%, the motor ensures high-performance operation for central air conditioner outdoor units. It operates within an ambient temperature range of -15~+50°C and a storage temperature range of -30~+60°C, adapting to various climatic conditions. Ball bearings ensure smooth rotation, and B-class insulation, along with IP42 protection, enhances safety and reliability in outdoor environments.
